03/2009
Cause: The drive unit did not accept the receive configuration data.
Alarm value (r2124, interpret decimal):
Return value of the receive configuration data check.
0: Configuration accepted.
1: Connection established to more drive objects than configured in the device. The drive objects for
process data exchange and their sequence were defined using p0978.
2: Too many data words for input or output to a drive object. A maximum of 16 words is permitted for
SERVO and VECTOR; and a maximum of 5 words for A_INFEED, TB30, TM31 and CU320.
3: Uneven number of bytes for input or output.
4: Setting data for synchronization not accepted.
5: Drive still not in cyclic operation.
6: Buffer system not accepted.
7: Cyclic channel length too short for this setting.
8: Cyclic channel address not initialized.
9: 3-buffer system not permitted.
10: DRIVE-CLiQ fault.
11: CU-Link fault.
12: CX32 not in cyclic operation.
Remedy: Check the receive configuration data.
Re alarm value = 1:
Check the list of the drive objects with process data exchange (p0978). With p0978[x] = 0, all of the
following drive objects in the list are excluded from the process data exchange.
201910 <location>PROFIBUS: Setpoint timeout
Message -
value:
Drive object: All objects
Reaction: A_INFEED: OFF2 (NONE, OFF1)
SERVO: OFF3 (IASC/DCBRAKE, NONE, OFF1, OFF2, STOP1, STOP2)
VECTOR: OFF3 (IASC/DCBRAKE, NONE, OFF1, OFF2, STOP1, STOP2)
Acknowledge: IMMEDIATELY
Cause: The receipt of setpoints from the PROFIBUS interface is interrupted because the bus connection is
interrupted or the PROFIBUS master is switched off or was set to the STOP state.
See also: p2047 (PROFIBUS additional monitoring time)
Remedy: Restore the bus connection and set the PROFIBUS master to RUN.

201911 <location>IF1: PB/PN clock cycle synchronous operation clock cycle
failure
Message -
value:
Drive object: All objects
Reaction: OFF1
Acknowledge: IMMEDIATELY
Cause: The global control telegram to synchronize the clock cycles has failed - in cyclic operation - for several
DP clock cycles or has violated the time grid specified in the parameterizing telegram over several
consecutive DP clock cycles (refer to the bus cycle time, Tdp and Tpllw).
Remedy: - check the PROFIBUS cables and connectors.
- check whether communication was briefly or permanently interrupted.
- check the bus and master for utilization level (e.g. bus cycle time Tdp was set too short).
Note:
IF1: Interface 1
PB: PROFIBUS
PN: PROFINET
